Bok- och grankonkurrens i Sydsverige : markegenskaper och naturlig föryngring

Sammanfattning: In southern Sweden, beech (Fagus silvatica) and spruce (Picea abies) are two species with similar demands on soil properties. With increased global warming and high acid deposition the future may bring larger areas were the two species are overlapping, competing for the same soil. The aim of this study was to compare spruce and beech concerning distribution, cultivation and soil properties. From available data comparisons were made between spruce and beech forests in Sweden. Soil analyses were made on samples from beech forest in southern Sweden, with and without natural regeneration of spruce. In the organic layer, beech forests had significantly higher pH and lower C/N-ratio compared to spruce forests. beech forests with spruce regeneration had significantly lower pH, lower CEC and lower BS in the organic layer than pure beech forests in the same area.
